  1. Multi link rear ends are good at hiding clunks and play. The noise the sometimes make are awfull but still it can be difficult to localize the culprit. And now it reminds me to do that front diff bushing on the M3, I've been avoiding it for a year.. I went for the Castrol LS 75w140 on my W201 after diff rebuild, with lsd and asd (variable lock hydraulically controlled by a module). Mercedes required some weird fluid. This stuff is cheap, works on all my Bimmers with lsd, extra pressure hypiod gears clutch pack lsd etc, so I put that in there and it was great. There are more expensive alternatives but I'd rather change the diff fluid more often
